Abstract

The utility model discloses a vacuum sealing drainage assembly which comprises a semi-permeable membrane, a drainage tube and a sponge layer. The sponge layer is attached to the inner surface of the semi-permeable membrane, a front end of the drainage tube is inserted into the sponge layer, a drainage tube support is arranged on the semi-permeable membrane, the drainage tube penetrates out from the drainage tube support, and a ribbon is bound on an outer wall of the drainage tube support. The inner diameter of the drainage tube support is matched with the drainage tube, two rubber sealing rings are arranged on an inner wall of the drainage tube support, and an adhesive layer is arranged on the inner surface of the semi-permeable membrane. The drainage pipe penetrates out from the drainage pipe support on the semi-permeable membrane, the rubber sealing rings are arranged on an inner wall of the drainage pipe support, the ribbon is bound on the outer wall, and sealing performance between the drainage pipe support and the drainage pipe is well guaranteed. The semi-permeable membrane is completely attached to a wounded portion and a part of normal skin around the wounded portion of a patient, vacuum can be formed at the wounded portion of the patient, partial microcirculation is improved, bacteria are restrained from growing, contamination is reduced, and healing of the wounded portion is quickened.

Description

The negative-pressure sealed drainage suit

Technical field

This utility model relates to a kind of wound face therapeutic appliance; Be specifically related to that a kind of patient's of being attached to wound face uses, can effectively remove drain district exudate and slough, improve local microcirculation and promote that tissue edema disappears; Stimulate the granulation tissue growth, quicken the drain suit of wound healing.

Background technology

The negative-pressure sealed drainage technology is the new technique that is used to treat wound surface that development in recent years is got up, and it utilizes biological semipermeable membrane to make the open wound sealing, uses the special negative pressure machine to produce certain negative pressure, acts on wound face through drainage tube and dressing.Prove that after deliberation this therapy can be quickened the blood circulation of wound site, significantly promote new vessels to get into wound surface; Stimulate the growth of granulation tissue, fully drain alleviates edema; Bacteria growing inhibiting reduces and pollutes, and can directly accelerate wound healing; Be a kind of efficient, simple, economical, promote the pure physiotherapy of wound healing.

The negative-pressure sealed drainage suit adopts the macromolecule medical sponge as the intermediary between negative-pressure drainage tube and wound surface, and wound surface seals with biological semipermeable membrane, under the vacuum suction machine effect, forms an airtight drainage system.During negative pressure treatment; Negative pressure can attract the exudate of wound surface fall timely; And can about 2-7 days change medicine one time, have that wound healing is fast, infection rate is low, fewer, the antibacterials of change dressings number of times are used less, avoided cross infection, alleviate the patient suffering; Shorten the hospital stays, reduce characteristics such as medical expenses.

Existing negative-pressure sealed drainage suit; Drainage tube is wrapped in the spongy layer, and the leading section of spongy layer and drainage tube is pressed in the below of biological semipermeable membrane, and this kind structure in use; Patient's wound face negative pressure weak effect; After service time is long, might can not produce negative pressure or negative pressure instability, directly influence curative effect at wound face.

The utility model content

The purpose of this utility model is to provide a kind of negative-pressure sealed drainage suit, and this negative-pressure sealed drainage sleeve structure is novel, and result of use is better.

This utility model to achieve these goals, the technical solution of employing is:

The negative-pressure sealed drainage suit comprises semipermeable membrane, drainage tube and spongy layer, and spongy layer is attached to the inner surface of semipermeable membrane; The leading section of drainage tube is inserted in the spongy layer; Semipermeable membrane is provided with the drainage tube bearing, and drainage tube passes from the drainage tube bearing, and bundle has band on the outer wall of drainage tube bearing.

Preferably, the internal diameter and the drainage tube of said drainage tube bearing are suitable, and two rubber seal are arranged on the inwall of drainage tube bearing.

Preferably, the inner surface of said semipermeable membrane is provided with adhesive-layer.

The beneficial effect of this utility model:

This kind negative-pressure sealed drainage suit, drainage tube is passed by the drainage tube bearing on the semipermeable membrane, on the drainage tube bearing inwall rubber seal is arranged, and bundle has band on the outer wall, has well guaranteed drainage tube bearing and drainage tube seal between the two.Semipermeable membrane is attached to patient's wound face fully, can be good at forming negative pressure in patient's wound site, and fully drain alleviates edema, reduces and pollutes, and bacteria growing inhibiting is accelerated the wound face healing.

Description of drawings

Fig. 1 is the structure diagram of negative-pressure sealed drainage suit.

The specific embodiment

Below in conjunction with accompanying drawing this utility model is elaborated:

In conjunction with Fig. 1; The negative-pressure sealed drainage suit comprises semipermeable membrane 1, drainage tube 2 and spongy layer 3, and spongy layer 3 is attached to the inner surface of semipermeable membrane 1; The leading section of drainage tube 2 is inserted in the spongy layer 3; Semipermeable membrane 1 is provided with drainage tube bearing 4, and drainage tube 2 passes from drainage tube bearing 4, and bundle has band 5 on the outer wall of drainage tube bearing 4.The internal diameter of said drainage tube bearing 4 and drainage tube 2 are suitable, and two rubber seal are arranged on the inwall of drainage tube bearing 4, and the inner surface of semipermeable membrane 1 is provided with adhesive-layer.

Certainly; Above-mentioned explanation is not to be the restriction to this utility model; This utility model also be not limited in above-mentioned for example, variation, remodeling, interpolation or replacement that the technical staff in present technique field is made in the essential scope of this utility model also should belong to the protection domain of this utility model.
